Prince Chun of the First Rank, or simply Prince Chun, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Chun peerage was not awarded "iron-cap" status, this meant that each successive bearer of the title would normally start off with a title downgraded by one rank vis-à-vis that held by his predecessor. However, the title would generally not be downgraded to any lower than a feng'en fuguo gong except under special circumstances.
The first bearer of the title was Yunyou (允祐; 1680–1730), the Kangxi Emperor's seventh son. In 1709, Yunyou was granted the title "Prince Chun of the Second Rank" by his father. He was promoted to "Prince Chun of the First Rank" in 1723 during the reign of his fourth brother, the Yongzheng Emperor. The title was passed down over seven generations and held by seven persons.
